In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0040] like Figure 1 As shown, a cleaning device suction head, corresponding to a preferred embodiment of the present invention, is used to clean a surface to be cleaned through methods such as vacuuming and mechanical friction. The surface to be cleaned can be a floor, and the cleaning device can be a vacuum cleaner. The cleaning device suction head may include components such as a main body shell 1, a tray 2, and a brush strip 3.

[0041] The main body shell 1 may include a lower end and an upper end opposite to each other along the height direction of the cleaning device suction head, with the lower end close to the surface to be cleaned and the upper end away from the surface to be cleaned. The lower end of the main body shell 1 may be provided with at least one suction port 11, which is used to suck up dust and other contaminants from the outside, so that the contaminants on the surface to be cleaned are sucked into the cleaning device suction head, thereby cleaning the surface to be cleaned.

[0042] Existing vacuum cleaner heads have elongated, narrow suction ports. The suction power provided by the connected motor and other components is limited, and the elongated port disperses the suction, resulting in reduced overall suction strength. (Refer to...) Figure 1 and Figure 3In the present application, the suction port 11 is recessed from the lower end of the main body shell 1 towards the upper end, and the size of the suction port 11 gradually changes from the lower end of the main body shell 1 towards the upper end. For example, the size of the suction port 11 gradually increases or gradually decreases from the lower end of the main body shell 1 towards the upper end, and preferably, the size of the suction port 11 gradually decreases from the lower end of the main body shell 1 towards the upper end. By setting the size of the suction port 11 to gradually change from the lower end of the main body shell 1 towards the upper end, the suction port 11 forms a horn-shaped structure, which can reduce the overall size of the suction port 11. A smaller suction port 11 can concentrate the suction force, thereby increasing the suction force at the suction port 11 under the condition that the power of the dust collection motor remains unchanged, so that the suction port 11 can more easily suck in large-sized contaminants, improving the cleaning effect of the cleaning device suction head. At the same time, it can also reduce the risk of large-sized contaminants moving to the mop plate 2 and contaminating the mop plate 2, reduce the cleaning or replacement frequency of the mop cloth on the mop plate 2, and improve the cleaning effect of the cleaning device suction head.

[0043] The suction port 11 can be provided in multiple numbers, and the size of each suction port 11 can gradually decrease from the lower end of the main body shell 1 towards the upper end. The multiple suction ports 11 are arranged at the same end of the main body shell 1 and are spaced apart along the circumference of the main body shell 1. By providing multiple suction ports 11, the suction area of the cleaning device suction head for sucking in contaminants can be increased, improving the cleaning efficiency of the cleaning device. Among them, the multiple suction ports 11 are arranged at the same end of the main body shell 1; for example, the main body shell 1 includes opposite front and rear ends along a first direction, and the multiple suction ports 11 are arranged at the front end of the main body shell 1. The first direction is specifically the front-to-back movement direction of the cleaning device suction head.

[0044] Referring to Figures 2 to 4 In some specific embodiments, the multiple suction ports 11 can include a first suction port 111 located at the middle of the main body shell 1 and a second suction port 112 located at the edge of the main body shell 1. In the cleaning device suction head, the connection channel 4 between the first suction port 111 located at the middle of the main body shell 1 and the dust collection motor is shorter, while the connection channel 4 between the second suction port 112 located at the edge of the main body shell 1 and the dust collection motor is longer, so the suction force at the second suction port 112 can be weaker than that at the first suction port 111. Moreover, when the cleaning device suction head is working, contaminants are mainly sucked into the cleaning device suction head through the middle of the main body shell 1, and contaminants located at the edge of the main body shell 1 are mainly small-particle contaminants such as floating dust. In the present embodiment, the size of the first suction port 111 can be larger than that of the second suction port 112, and the smaller size of the second suction port 112 can ensure that the suction force is concentrated, thereby making the suction force at the second suction port 112 not significantly weaker than that at the first suction port 111, ensuring the cleaning effect of the second suction port 112.

[0045] The first suction port 111 and the second suction port 112 can be connected to an external dust collection motor through a connecting channel 4. One end of the connecting channel 4 extends to the lower end of the main body shell 1 and penetrates the main body shell 1 to form a connecting hole 41. The connecting channel 4 provides suction to the space connected to the connecting hole 41 through the dust collection motor. The connecting hole 41 is located in the middle of the main body shell 1, so the distance between the first suction port 111 and the connecting hole 41 is shorter than the distance between the second suction port 112 and the connecting hole 41. The connecting hole 41 can be directly or indirectly connected to the first suction port 111 and the second suction port 112. The middle of the main body shell 1 refers to the middle of the main body shell 1 in the second direction, and the edge of the main body shell 1 refers to the edge of the main body shell 1 in the second direction. The second direction is perpendicular to the first direction, and the second direction can be the width direction of the cleaning device suction head.

[0046] Further referring to Figure 8 and Figure 9 The suction port 11 includes a bottom portion 11a constituting the outer surface of the lower end portion of the main body shell 1. In the height direction, the bottom portion 11a is convex toward the upper end of the main body shell 1, so that the size of the suction port 11 can gradually increase from the lower end toward the upper end of the main body shell 1, to allow the contaminants to enter the opening through the suction port. In the first direction, the bottom portion 11a is convex toward the connecting hole 41, so that the suction port 11 has two opposite side surfaces 11b, and the suction port 11 also has a top surface 11c connecting the two side surfaces 11b. The top surface 11c gradually extends toward the surface to be cleaned in the first direction. By providing the side surfaces 11b and the top surface 11c, the size of the suction port 11 can gradually decrease from the front end toward the rear end of the main body shell 1, so that the suction port 11 can extract more contaminants. In the prior art, the size of the suction port 11 is usually gradually reduced to increase the fluid flow speed at the suction port, but it also makes it difficult for large-particle contaminants to pass through, thereby causing blockage. The present patent solves the problem of easy blockage of the suction port 11 near the opening 12 by overlapping the top of the bottom portion 11a with the end of the top surface 11c.

[0047] Referring to Figure 2 and Figure 12In some embodiments, the connection channel 4 formed by the main body shell 1 serves as a fluid channel 6 for the air flow and the pollutants carried by the air flow. The connection hole 41 at one end of the connection channel 4 is in communication with the suction port 11 through the opening 12. The suction port 11 can facilitate the suction of pollutants such as dust into the opening 12, which will then flow into the connection channel 4 through the suction port 11, the opening 12, and the connection hole 41, and then flow along the fluid channel 6 to the dust collection motor. The opening 12 can include a main opening 121 in the middle of the cleaning device suction head and side openings 122 on the sides of the cleaning device suction head and in communication with the main opening 121. In the first direction, the back side of the main opening 121 extends towards the connection hole 41. Since the connection hole 41 is located in the middle of the main opening 121, the middle of the main opening 121 extends a shorter distance from the connection hole 41, while the sides of the main opening 121 extend a longer distance from the connection hole 41. By extending the back side of the main opening 121 towards the connection hole 41, the main opening 121 forms a structure that extends backward in the middle and upward at both ends, with the width of the opening 12 being the largest in the middle and gradually decreasing towards the sides. The middle of the main opening 121 is closest to the fluid channel 6, and thus has the largest suction force. Therefore, increasing the width of the middle of the opening 12 can ensure that the suction force meets the demand. The sides of the main opening 121 are farther away from the fluid channel 6, and thus have a reduced suction force. Therefore, decreasing the width of the sides of the main opening 121 can ensure that the suction force meets the demand.

[0048] To improve the cleaning ability of the corners of the cleaning device suction head, the two ends of the main opening 121 are connected to the side openings 122. The side openings 122 extend from the ends of the main opening 121 towards the back side. The side openings 122 can be used in cooperation with the second suction port 112 to clean the corner area of the cleaning device suction head, thereby improving the cleaning ability of the corners of the cleaning device. In particular, the side openings 122 extend backwards beyond the main opening 121, so that the back end of the side openings 122 is further back than the back end of the main opening 121, further improving the cleaning ability of the side openings 122, i.e., the corners of the cleaning device suction head.

[0049] Further reference is made to Figure 10 and Figure 11The opening 12 includes a front inner wall 12a and a rear side wall 12b arranged in front of and behind the opening 12 in the first direction. The distance between the front inner wall 12a and the rear side wall 12b is the width of the opening 12. In the middle of the cleaning device suction head, the distance between the rear side wall 12b and the front inner wall 12a is the largest, i.e., the width of the opening 12 is the largest. At both ends of the opening 12, the distance between the rear side wall 12b and the front inner wall 12a is the smallest, i.e., the width of the opening 12 is the smallest. The front inner wall 12a is provided with a protrusion 121a corresponding to the suction port 11. In this embodiment, the second suction port 112 corresponds to the smaller width of the opening 12, and in order to ensure the flow of fluid, the second suction port 112 is not provided with a top surface 11c and a side surface 11b. In other embodiments, when the opening width is larger, the second suction port 112 can be provided with a top surface 11c and a side surface 11b.

[0050] Referring to Figure 1 and Figure 2 The brush strip 3 is mounted to the main body shell 1, and can be mounted to the lower end of the main body shell 1. The brush strip 3 can divide the main body shell 1 into the opening 12 and the second space 32, which are arranged on opposite sides of the brush strip 3 along the first direction. The opening 12 can be in communication with the connection hole 41 formed by the suction port 11 and the connection channel 4. The second space 32 can be used to accommodate the mop 2. The brush strip 3 can include dense bristles that separate the opening 12 and the second space 32. The first suction port 111 and the second suction port 112 are respectively in communication with the connection hole 41 through the opening 12, and the external contaminants are sucked into the opening 12 from the first suction port 111 or the second suction port 112, and then enter the connection channel 4 through the opening 12. The profile of the brush strip 3 is adapted to the profile of the opening 12, i.e., the extension profile of the brush strip 3 is the same as the corresponding part of the profile of the opening 12. In addition, the plurality of suction ports 11 can also be adapted to the profile of the opening 12, for example, the plurality of suction ports 11 are arranged in sequence along the part of the profile of the opening 12. The profiles of the plurality of suction ports 11 and the brush strip 3 together enclose the opening 12.

[0051] By using the brush strip 3 to separate the opening 12 and the second space 32, it can prevent the contaminants at the opening 12 that are not sucked into the fluid channel 6 from moving into the second space 32 to contaminate the mop 2. In addition, the separation of the brush strip 3 can also concentrate the suction force provided by the connection channel 4 in the opening 12, improve the vacuum degree in the opening 12, improve the suction force of the suction port 11, and further improve the cleaning effect of the cleaning device suction head.

[0052] Referring to Figure 4 and Figure 6The end of the brush strip 3 in the second direction can climb up to the side wall of the main body shell 1 to improve the cleaning ability of the corner of the cleaning device suction head. Specifically, the brush strip 3 comprises a first part and a second part. The first part of the brush strip 3 is located below the main body shell 1, one end of the first part extends to one side of the main body shell 1, and the other end of the first part extends to the other side of the main body shell 1. The second part of the brush strip 3 climbs up to the side wall of the main body shell 1 from the end of the first part in the height direction. The second part of the brush strip 3 can be provided with two, each second part is connected with one end of the first part, and the two second parts are located on opposite sides of the main body shell 1.

[0053] The part of the brush strip 3 that climbs up to the side wall of the main body shell 1 can protrude from the side wall of the main body shell 1, so that when the main body shell 1 is about to collide with other objects, for example, when the main body shell 1 is about to collide with the skirting of a wall, the brush strip 3 will first contact the skirting of the wall, thereby preventing the main body shell 1 from colliding with the skirting, or reducing the damage to the main body shell 1 and the skirting when the main body shell 1 collides with the skirting. The second part of the brush strip 3 is adjacent to the second suction port 112, so that the suction force at the second suction port 112 is blocked by the second part of the brush strip 3 and is concentrated at the second suction port 112, thereby improving the suction ability of the second suction port 112.

[0054] The brush strip 3 comprises a main body part 35 arranged in the middle part of the main body shell 1, a climbing part 33 for climbing up to the side wall of the main body shell 1, and an extension part 34 connecting the main body part 35 and the climbing part 33. The main body part 35 and the extension part 34 of the brush strip 3 are arranged in the height direction and are stacked with the main body shell 1, and the main body part 35 and the extension part 34 of the brush strip 3 form the first part of the brush strip 3. The main body part 35 and the extension part 34 are adapted to the contour of the opening 12. Specifically, the main body part 35 is adapted to the contour of the main opening 121, and the middle part of the main body part 35 extends backward correspondingly to the main opening 121, and the main body part 35 forms a structure with the middle part extending backward and the two ends upward. The extension part 34 extends toward the rear side from the end of the main body part 35 corresponding to the contour of the side opening 122. The climbing part 33 of the brush strip 3 forms the second part of the brush strip 3, and the climbing part 33 climbs up to the side wall of the main body shell 1 from the end of the extension part 34.

[0055] The brush strip 3 can be a one-piece structure. Alternatively, the brush strip 3 can be provided as a split structure. Specifically, referring to Figure 7The main body 35, the climbing portion 33 and the extension portion 34 of the brush strip 3 can be separately formed and configured in a split structure. The connection portion between the main body 35 and the extension portion 34 of the brush strip 3 can have a large angle change, for example, the main body 35 is configured to extend backward in the middle and upward at both ends, and the extension portion 34 is configured to be an arc structure formed by bending backward from the end of the main body 35. The curvature change of the main body 35 as a whole and the curvature change of the extension portion 34 can be small, so as to facilitate the processing of the main body 35 and the extension portion 34. The climbing portion 33 and the extension portion 34 can be provided with two respectively, and the two climbing portions 33 are provided on opposite sides of the main body 1, and each climbing portion 33 is connected with the main body 35 through a corresponding extension portion 34.

[0056] The mop plate 2 is rotatably installed at the lower end of the main body 1, and the mop plate 2 can be in contact with the surface to be cleaned, and the mop plate 2 can clean the surface to be cleaned by mechanical friction, for example, the mop plate 2 cleans the surface to be cleaned by friction between the mop plate 2 and the surface to be cleaned when the mop plate 2 rotates. The mop plate 2 can be provided with a plurality of mop plates 2, and the plurality of mop plates 2 are arranged in the second direction. In the embodiment, the mop plate 2 can be provided with two.

[0057] Referring to Figure 2 In some specific embodiments, the first suction port 111 and the second suction port 112 can be provided with a plurality of first suction ports 111 and a plurality of second suction ports 112 respectively. The plurality of first suction ports 111 are arranged in the first direction, and the plurality of second suction ports 112 are arranged in the second direction. Therefore, the plurality of first suction ports 111 and the plurality of second suction ports 112 enclose a distribution space. The distribution space, the opening 12 and the mop plate 2 are arranged in the first direction in sequence.

[0058] The opening 12 can partially overlap the mop plate 2 in the first direction, and the maximum length H1 of the portion of the side opening 122 overlapping the mop plate 2 in the first direction, the maximum length H2 of the portion of the main opening 121 overlapping the mop plate 2 in the first direction, and the portion of the main opening 121 not overlapping the mop plate 2 in the embodiment. The maximum length H (i.e. H1) of the portion of the mop plate 2 overlapping the opening 12 in the first direction is 0.05-0.5 times the diameter D of the mop plate 2, so as to maximize the cleaning capacity of the opening 12 without affecting the transverse size of the cleaning device suction head. The maximum length H of the portion of the mop plate 2 overlapping the opening 12 in the first direction can be 13-19 mm; and the diameter D of the mop plate 2 can be 120-180 mm.

[0059] Further referring to Figure 10In some embodiments, the cleaning device head is further provided with a front wheel 7, the second space 32 is provided with a front wheel mounting groove 13, and the front wheel 7 is fixed in the front wheel mounting groove 13 through a metal shaft or the like, so that the front wheel 7 can rotate with the main body shell 1; and a part of the front wheel 7 can protrude out of the front wheel mounting groove 13 to contact the surface to be cleaned. When it is needed to drag the cleaning device head to move, the front wheel 7 contacts the surface to be cleaned and rotates around the metal shaft to reduce the resistance when the cleaning device head 100 moves relative to the surface to be cleaned. The front wheel mounting groove 13 is arranged between the mop plate 2 and the opening 12, and specifically, the front wheel mounting groove 13 is arranged between the brush strip 3 and the mop plate 2. Through the blockage of the brush strip 3, the pollutants located at the opening 12 cannot or are less likely to move to the front wheel 7, and even if a small part of the pollutants is sucked into the cleaning device head 100 at the opening 12, the small part of the pollutants has less impact on the front wheel 7, thereby reducing the risk that the front wheel 7 is contaminated by dirt and cannot rotate normally.

[0060] Referring to Figure 3 and Figure 5 In some embodiments, the cleaning device head is further provided with a searchlight assembly 5, and the searchlight assembly 5 includes an illuminating lamp 51 capable of illuminating.
